Be it known that we, FRAXK K. Howie-errand ARTHUR J. Mason, citizens of the United States. residing-at Chicago, in the county of Cook 8115 $tate of Illinois, have invented cer-' tain new and useful Improvements in' Devices for Obtaining Rapid and Accurate Loading of, Railroad-Cars and the Like, of which the following is: specification.- v ()ur invention relates tea new andimproved means for ohltaining both amid and an accurate loading of railroad-cars and otherfreightcarriers.-

Railroad-cars and like carriers adapted for the tmnsgmrtation of coaL- ore, with, and similar. loose and more or less. granular material are'atthe pres'eutday extensively loaded 7' liv,- means of self-loading grabs or buckets of large capacity suspended from lHiL'lL'LiCIHDLS, and like overhead supports. the gmh pk'klng up a load of material from a stock-pile or an i excavation and traveling with it to a position directlv ever the ear. whence its load is dischargeil into the latter. This manner of load ing unwmnomlcal in that the operatorm or: der to avoid overloading is frequently required as the loading of the car nears completion to make trips with the loading grab or I bucket one-halter one-quarter full. Furthermore. during the intervalsbetween the withdrawal of a loaded carand the intrmiueiion of 'an en:pt v car to its place the loading-grab is required to be partially or entirelv idle.

A leading object of our invention, therefore, is to a'void the-s c objections through theemplqvme'nt of a tem mriugv receptacle capable of holding, preferably, several car-loads between the loading-grab and the car or other carrier to be loaded, which receptacle permits the grab to remain coutinu'ouslya; work, while in wnneetion with receptacle means are provided for permitting or effecting the withdrawal therefrom of desired and regulable nouuts of material into the cars placed therebeneath. It. resultsfrom such an ar rangemen-t not-only that the loading-gml', .na c be kept cont-inously at work replenishing the temporary rmeptaele. but the individual cars may themselves be loaded'mueh more rapidly by a continuous discharge of material from of carsloaded appreciably beyond their maxi 5 'munitested capac ty.

' car, in order that the maximum etliiency-and economy may be serve".i in the transportation- 9g; offreight. Obviously it ie uneeomunieal 't0- draw ears loaded appreciably below their minimum carrying capacity. and it is likewise dangerous to attempt the transportation For these reasons l a freight-carriers endeavor to secure a loading of cars within certain specified mininum and maximum weights, according to the tested ea: paeityv of eaehcar. and if the load exceeds the 7 maximum or i'allshelow the minimum much delay is incurred by rearwri of the nee'essar, re-- loadingor readjustment of the load before the car will he accept-ed for ma nsportation. 'hen the loading of cars is :u-mmplished diiect by self-loading grabs or buckets, such grabs or buckets freq uent l taking up and depositingas high as fifteen tons on each trip. the restrictions imposed by tlu"railroaul.-. as to the maximum and iniuiunuu limits of the \veightof theioad 8O hamper t he work of loading. For instance, it

will be seen that when the grab is delivering direct to the ca rs the operatormust constantly hear in mind the capacity of the particular I cartlien being-loaded ancha; ahove'mentioned, 35' must frequently take up half or quarter loads, so as not to overload the ear. Even with long experience. it is very ditlieult. to estimate or guess with any fair degrceof accuracy when the car has receiveda proper and suliicient load. since the material varies greatly in 'sp ciiic gravity, and the fornndimensions, and capacity of diflerent freight-cars also vary within a wide range.v Another important object of our presentin vention.'t-h refore, is to obviate the condi-q tions at present existing under which great care is required to be e'aezciscd in the loading of cars in order to avoid violation of the-rules i,

of the railroads and consequent delay in transg;
